GWTP＆Singleton

我有一個簡單的主持人。宣佈調用類的單GWTP＆Singleton

private RandomString randomString = RandomString.getInstance();

當裝配行家我有錯誤

RandomString ...

private RandomString() { 

    } 

    private static class RandomStringHolder { 
     private final static RandomString instance = new RandomString(); 
    } 

    public static RandomString getInstance() { 
     return RandomStringHolder.instance; 
    } 
...

有了它可以連接？沒有聲明RandomString項目將

您的錯誤與RandomString無關。錯誤表示您缺少一個@Inject帶註釋的構造函數。

確保您的PacketPageView和PacketPagePresenter具有註釋爲@Inject的空構造函數。

@Inject 
public PacketPagePresenter() { 
}

@Inject \t PacketPagePresenter（EventBus eventBus，MyView的視圖，MYPROXY代理）{ \t \t超級（eventBus ，view，proxy，ApplicationPresenter.SLOT_SetMainContent）; \t \t init（）; \t}沒有聲明RandomString項目版本 – LeshaRB

你是否在'init（）'中使用'RandomString'。即使你這樣做，也不應該有所作爲。 –

錯誤是在這個代碼

private String convertMStoTime(long millis) { 
    //return null; 
    return String.format(
    "%02d:%02d:%02d", 
    TimeUnit.MILLISECONDS.toHours(millis), 
    TimeUnit.MILLISECONDS.toMinutes(millis) 
    - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS 
    .toHours(millis)), 
    TimeUnit.MILLISECONDS.toSeconds(millis) 
    - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS 
    .toMinutes(millis))); 
}

在GWT TIMEUNIT dont'realese
